Rural Hybrid Energy Enterprise Systems (RHEES) is a research partnership between 6 UK and 7 Indian Universities. The aim of this project is to develop best practise at a smaller community scale which makes use of hybrid and combinations of biofuels. The idea is to improve rural energy availability, equity of cost and to generate an economic stimulus from the desire to provide greater energy security and reduced environmental impact. Our part of the project is AD and here we describe the typical Assam design. We summarise how a novel gas monitoring device for remotely controlled, autonomous monitoring of AD might avoid shock loadings from heterogeneous feedstocks.
